I was pleasantly surprised by the videos. They are spot on for describing the leveling and gameplay experience for the first 20 levels of the game to someone who is either new to video games in general or MMORPGs in particular. I'd pass along the link to friends who haven't touched a video game since college when video games as a genre of entertainment were only starting to take off in the mid '80s. Meanwhile, most of my high-school friends are already grandparents.
They are not tutorials for current players. They are not tutorials for players who are coming into the game who already have experience playing another MMORPG. They are a marketing tool. The sooner folks realize that an introduction to the basics for a game they have never played is something new players will find useful, the better.
For experienced or current players ... the only true guides and videos out there are mostly
* massively outdated
* aimed at a hard-core player audience
* mostly blank when it comes to discussing the 1-90 player experience
That last includes discussions of mechanics, instances, using the market board effectively to purchase (not sell) something, and the best of the non-max-level rotations.
It took me 5 years to get to the point where I could play Black Mage with any specific level of expertise past ARR. The tools and rotations kept changing every expansion and 'guides' stuck to how to play your best at max-level in raids. I really don't need a string of icons showing the 2-minute opener for a job at end game as "here's the rotation, but only until the next expansion comes out. Don't use it at lower levels, because most of the stuff we discuss requires you to get to 70 first"
I have yet to see a content creator discuss the best means of leveling from 1 to 50, for instance. I include sites such as icy-veins, which looks more and more like wowhead every day. Most of the people who visit these forums have already "been there-done that-threw away the T-shirt".
